DETAILED DESCRIPTION

The embodiments of the present disclosure are described below in detail.Examples of the embodiments are shown in the accompanying drawings, andsame or similar reference signs in all the accompanying drawingsindicate same or similar components or components having same or similarfunctions. The embodiments described below with reference to theaccompanying drawings are exemplary, and are intended to explain thepresent disclosure and cannot be construed as a limitation to thepresent disclosure.

The following describes a railway vehicle 100 according to theembodiments of the present disclosure with reference to FIG. 1 to FIG.27 . The railway vehicle 100 is a straddle-type monorail vehicle (notshown in the figure). In the following description of this application,take the railway vehicle 100 as the straddle-type monorail vehicle as anexample. Certainly, a person skilled in the art may understand that, therailway vehicle 100 is another type of railway vehicle, which is notlimited to the straddle-type monorail vehicle.

As shown in FIG. 1 to FIG. 27 , the railway vehicle 100 according to anembodiment of a first aspect of the present disclosure includes a floor1 and a wheel cover 3.

Specifically, an opening portion 11 is provided on the floor 1. Twowheel removal and mounting floor panels 5 are disposed in the openingportion 11, a sub-opening portion is defined between the two wheelremoval and mounting floor panels 5, a wheel 2 is disposed at thesub-opening portion, a part of the wheel 2 passes through thesub-opening portion and protrudes from an upper surface of the floor 1,and the two wheel removal and mounting floor panels 5 are respectivelylocated on two sides of the wheel 2 in a front-rear direction of therailway vehicle 100. Both the two wheel removal and mounting floorpanels 5 are detachably connected to the floor 1. The wheel cover 3covers an upper side of the wheel 2 and the wheel cover 3 is connectedto the two wheel removal and mounting floor panels 5.

For example, referring to FIG. 1 to FIG. 3 , FIG. 5 , and FIG. 16 , thefloor 1 extends in a horizontal direction, and the opening portion 11may run through the floor 1 in an up-down direction. The two wheelremoval and mounting floor panels 5 are disposed on two sides of theopening portion 11 in a length direction of the floor 1 at intervals. Inthis case, a width of the sub-opening portion in the length direction ofthe floor 1 is less than a width of the opening portion 11 in the lengthdirection of the floor 1. The wheel 2 is disposed at the sub-openingportion through penetration, an upper part of the wheel 2 is locatedabove the floor 1, and a lower part of the wheel 2 is located below thefloor 1. Therefore, by disposing the two wheel removal and mountingfloor panels 5, an area of the entire floor 1 is increased, and byfixing the wheel cover 3 to the two wheel removal and mounting floorpanels 5, a volume of the wheel cover 3 is reduced and a weight and anoccupied space of the wheel cover are reduced, thereby implementingmounting of a small wheel cover and relatively increasing a space for apassenger. When the railway vehicle 100 is a straddle-type monorailvehicle, in a case of a same quantity of passengers, this solution canreduce a length of the entire vehicle, reduce a weight of the entirevehicle, and further improve the performance of the entire vehicle. Inaddition, distances between the wheel 2 and the two wheel removal andmounting floor panels 5 are relatively short, and a wheel space (thatis, the sub-opening portion) reserved on a vehicle body of the railwayvehicle such as the straddle-type monorail vehicle may be reduced, sothat noise in the vehicle can be reduced, thereby improving the comfortof seat for passengers. The wheel 2 may be a walking wheel of therailway vehicle such as the straddle-type monorail vehicle.

When the wheel 2 needs to be removed, the wheel cover 3 may be firstremoved, and then the two wheel removal and mounting floor panels 5 areremoved. After a sufficient space for removing the wheel 2 is reserved,the wheel 2 is removed finally. Conversely, when the wheel 2 is mounted,the wheel 2 may be first mounted, then the two wheel removal andmounting floor panels 5 are mounted, and finally the wheel cover 3 ismounted. Therefore, the wheel 2 can be removed and mounted in thevehicle. Compared with a conventional manner of changing a wheel outsidethe vehicle, the manner of removing and mounting the wheel in thevehicle is convenient in removal and mounting and is time-saving andlabor-saving.

According to the railway vehicle 100 provided in the embodiments of thepresent disclosure, two detachable wheel removal and mounting floorpanels 5 located on two sides of a wheel 2 in a radial direction aredisposed, a part of the wheel 2 may pass through a sub-opening portionbetween the two wheel removal and mounting floor panels 5, and a wheelcover 3 is connected to the two wheel removal and mounting floor panels5, so that an area of the entire floor 1 is increased and an occupiedspace of the wheel cover can be relatively reduced, to reduce a weightof the wheel cover 3. When the railway vehicle 100 is a straddle-typemonorail vehicle, the wheel 2 is removed and mounted in the vehicle, aweight of the railway vehicle such as the straddle-type monorail vehicleis reduced, the performance of the railway vehicle such as thestraddle-type monorail vehicle is improved, and a wheel space reservedon a vehicle body is reduced, thereby reducing noise in the vehicle andimproving the comfort of seat for passengers.

According to some embodiments of the present disclosure, as shown inFIG. 10 and FIG. 11 , a central axis of the wheel 2 is lower than anupper surface of the floor 1. In this case, the central axis of thewheel 2 is located below a horizontal plane of the floor 1. A size of apart of the wheel 2 located above the floor 1 is less than a size of apart of the wheel located below the floor 1. Therefore, a part of thewheel 2 such as a walking wheel protruding from the floor 1 isrelatively small, so that a relatively low floor is implemented and aproportion of a passenger space occupied by the protruding part of thewalking wheel is reduced, to improve the comfort of seat. Referring toFIG. 8 , a distance between the two wheel removal and mounting floorpanels 5 is less than a diameter of the wheel 2 in a length direction ofthe floor 1. Such arrangement can further increase the area of theentire floor 1 and reduce the size of the part of the wheel 2 protrudingfrom the floor 1, so that the occupied space of the wheel cover 3 isfurther reduced and the weight of the wheel cover 3 is further reduced.Therefore, the wheel space reserved on the vehicle body is furtherreduced, the noise in the vehicle is further reduced, and the structureof the entire railway vehicle such as the straddle-type monorail vehiclecan be more compact, thereby further improving the performance of therailway vehicle such as the straddle-type monorail vehicle.

Optionally, a maximum width of the opening portion 11 is greater thanthe diameter of wheels 2 in the length direction of the floor 1.Therefore, after the two wheel removal and mounting floor panels 5 areremoved, the wheel 2 can be further conveniently removed in the vehicle.Optionally, a longitudinal width of the opening portion 11 is greaterthan the diameter of the wheel 2 by at least 100 mm or more. Because thewheel 2 has a large weight, which is about 200 kg, the wheel 2 has ashaking amount when the wheel 2 is removed, and such arrangement betterfacilitates removal of the wheel 2.

According to some embodiments of the present disclosure, as shown inFIG. 10 and FIG. 11 , a step structure 13 is disposed on an edge of thefloor 1 located at the opening portion 11, and one side of each wheelremoval and mounting floor panel 5 away from the wheel 2 is disposed onthe step structure 13, and an upper surface of an overhauling floorpanel 4 is flush with the upper surface of the floor 1. For example, thestep structure 13 may include a first upper surface 131 and a secondupper surface 132 that are not located on a same plane. The first uppersurface 131 is higher than the second upper surface 132 and the firstupper surface 131 is located on one side of the second upper surface 132away from the wheel 2. During mounting, a part of the wheel removal andmounting floor panel 5 extends to an upper side of the second uppersurface 132 and matches the second upper surface 132, and an uppersurface of the wheel removal and mounting floor panel 5 is flush withthe first upper surface 131. Therefore, it can be effectively ensuredthat the entire floor 1 is located on the same plane.

According to further embodiments of the present disclosure, referringFIG. 10 and FIG. 11 , a sealing member 124 is disposed between eachwheel removal and mounting floor panel 5 and the floor 1. For example,in examples of FIG. 10 and FIG. 11 , one side of each wheel removal andmounting floor panel 5 away from the wheel 2 extends to the upper sideof the floor 1 such as the second upper surface 132. The sealing member124 is disposed between a lower surface of one side of each wheelremoval and mounting floor panel 5 away from the wheel 2 and the secondupper surface 132 of the floor 1. With such arrangement, one side ofeach wheel removal and mounting floor panel 5 away from the wheel 2 maybe propped to the floor 1, noise transmission can be reduced, andmounting of the sealing member 124 is facilitated. Because the sealingmember 124 may seal a gap between the wheel removal and mounting floorpanel 5 and the floor 1, noise from a lower vehicle body of the railwayvehicle such as the straddle-type monorail vehicle can be effectivelyisolated.

Optionally, the sealing member 124 is a sealing rubber member. Forexample, the sealing member 124 may be a sealing rubber pad. Due toelasticity, a rubber structure can better seal the gap between the wheelremoval and mounting floor panel 5 and the floor 1, to achieve a goodsound insulation effect. However, the present disclosure is not limitedthereto.

According to some embodiments of the present disclosure, referring toFIG. 1 to FIG. 3 and FIG. 12 to FIG. 14 , a seat 6 is disposed on thewheel cover 3. The seat 6 is configured for a passenger to sit on. Sucharrangement effectively utilizes a space occupied by the wheel 2protruding from the floor 1. Specifically, for example, in examples ofFIG. 1 to FIG. 3 and FIG. 12 to FIG. 14 , the seat 6 is fixedlyconnected to the top of the wheel cover 3, the wheel cover 3 covers anupper side of the wheel 2, and the wheel cover 3 and the seat 6 aredetachably connected to the floor 1 as a whole. In this case, the wheelcover 3 and the seat 6 may be an integrated structure, and the seat 6and the wheel cover 3 may be integrally formed. Certainly, the seat 6and the wheel cover 3 may alternatively be separately processed andformed and then connected as a whole through welding or the like.Therefore, the wheel cover 3 is designed to be compatible with the seat6, and the wheel cover 3 and the seat 6 as a whole can simultaneouslyprotect the wheel 2 and allow passengers to take. When requiring to bemounted or removed, the wheel cover 3 and the seat 6 only need to bemounted on the floor 1 or removed from the floor 1 as a whole. Comparedwith a conventional manner of requiring to first remove the seat andthen remove the wheel cover, the manner is convenient in removal and istime-saving and labor-saving without a problem of destroying a mountingstructure between the seat and the wheel cover and can implementmounting and removal of the wheel 2 in a compartment.

Further, as shown in FIG. 15 , an accommodating space 32 with the bottombeing open and concave upward is formed on the wheel cover 3, and theaccommodating space 32 is configured to accommodate a part of the wheel2. Therefore, a part of the wheel 2 protruding from an upper surface ofthe floor 1 may be well covered by the wheel cover 3.

Optionally, referring to FIG. 15 , a top wall of the accommodating space32 is formed as an arc-shaped wall adapted to the shape of the wheel 2.For example, the wheel cover 3 is formed as an upwardly protrudingarch-shaped structure, which is preferably adapted to the shape of thewheel 2. With this arrangement, it is ensured that the part of the wheel2 can be well accommodated in the accommodating space 32, and the spaceoccupied by the wheel cover 3 in the compartment can be relativelyreduced.

Certainly, the present disclosure is not limited thereto. The wheelcover 3 may further be formed in the form of seat 6 (not shown in thefigure). For example, the wheel cover 3 and the seat 6 as a whole mayalso be formed as a seat in an upper part, and the bottom of the wheelcover 3 and the seat 6 as a whole is provided with an upwardly concaveportion, where a part of the wheel 2 is located in the concave portion.Specifically, the wheel cover 3 may include a seat part and a backrestpart. The seat part covers the upper side of the wheel 2, the concaveportion for accommodating the part of the wheel 2 is formed on thebottom of the seat part, a top surface of the seat part is a horizontalplane for the passenger to sit, and the backrest part extends upwardfrom the top surface of the seat part for the passenger to recline. Thewheel cover 3 may be a hollow structure with the bottom being open. Inthis case, the concave portion below the wheel cover 3 is configured toaccommodate the part of the wheel 2 protruding from the upper surface ofthe floor 1, and an upper part of the wheel cover 3 is for the passengerto directly sit. With this arrangement, the wheel cover 3 can be maderelatively small and has a light weight.

Optionally, as shown in FIG. 16 to FIG. 20 , the wheel cover 3 and theseat 6 are collectively referred to as a wheel cover and seat assembly 7as a whole. The wheel cover and seat assembly 7 is detachably connectedto the floor 1 by a bolt structure 8. Therefore, removal and mountingare convenient, and the connection through the bolt structure 8 isreliable, which is suitable for mass production and low in cost.

Further, referring to FIG. 16 to FIG. 20 , the bolt structure 8 islocated in the wheel cover and seat assembly 7. A wheel cover mountingopening 33 is formed in a lower portion of the wheel cover and seatassembly 7. The wheel cover mounting opening 33 is adjacent to the boltstructure 8, and a detachable sealing plate 34 is disposed at the wheelcover mounting opening 33. Herein, it should be noted that, a direction“inside” may be understood as a direction toward an inner center of thewheel cover and seat assembly 7, and a direction opposite to the“inside” is defined as “outside”, that is, a direction away from theinner center of the wheel cover and seat assembly 7. With thisarrangement, the bolt structure 8 may be well hidden inside the wheelcover and seat assembly 7, to ensure the compactness of the entirerailway vehicle 100. During removal and mounting, the sealing plate 34at the opening portion 11 may be opened, to tighten or loosen the boltstructure 8.

Specifically, as shown in FIG. 21 to FIG. 25 , the sealing plate 34 maybe fixedly connected to at least one fastener 341. The fastener 341includes a rod portion 3411 and an end portion 3412, where one end ofthe rod portion 3411 is connected to the sealing plate 34 and the endportion 3412 is connected to the other end of the rod portion 3411. Amaximum size of the end portion 3412 in a cross section of the rodportion 3411 is greater than a maximum size of the rod portion 3411 inthe cross section of the rod portion 3411, and the end portion 3412 maybe formed as a long strip shape. At least one mounting plate 331 isdisposed at a position of the wheel cover and seat assembly 7corresponding to the wheel cover mounting opening 33, a lockingstructure 332 is disposed on the mounting plate 331, and an elongatedhole 3321 adapted to a shape of the end portion 3412 is formed in thelocking structure 332. During mounting, after passing through theelongated hole 3321 on the locking structure 332 on the mounting plate331, the end portion 3412 of the fastener 341 on the sealing plate 34rotates by a specific angle. In this case, the end portion 3412 isstaggered with the elongated hole 3321 on the locking structure 332, toreliably mount the sealing plate 34 at the wheel cover mounting opening33. During removal, only the fastener 341 needs to be rotated, so thatthe end portion 3412 of the fastener is aligned with the elongated hole3321 of the locking structure 332. Subsequently, the sealing plate 34 isremoved outward. In this case, the fastener 341 is withdrawn from theelongated hole 3321 of the locking structure 332 and the mounting plate331.

Certainly, the bolt structure 8 may also be located outside the wheelcover and seat assembly 7. A groove with the top being open is formed inthe floor 1, the bolt structure 8 is located in the groove, and adetachable cover plate (not shown in the figure) is disposed on the topof the groove. Therefore, the bolt structure 8 is arranged outside thewheel cover and seat assembly 7, to facilitate removal and mounting.Disposing of the cover plate allows the bolt structure 8 to be wellhidden below the cover plate, which can similarly ensure the aestheticsof the entire railway vehicle 100.

It can be understood that the sealing plate 34 and the cover plate mayfurther be pivotally connected to a corresponding position by a hingestructure or the like, or may be clamped through a buckle structure orthe like. However, the present disclosure is not limited thereto.

Specifically, referring to FIG. 16 , FIG. 17 , and FIG. 18 , the boltstructure 8 includes: a first connecting member 81, a second connectingmember 82, and at least one bolt 83. The first connecting member 81 isdisposed on the floor 1, a C-shaped groove 811 with the top being openis formed in the first connecting member 81, at least one threadedconnector is disposed in the C-shaped groove 811, the second connectingmember 82 is disposed on the wheel cover and seat assembly 7, aconnecting plate 821 is disposed at a free end of the second connectingmember 82, the connecting plate 821 is supported on a top surface of thefirst connecting member 81, and the bolt 83 runs through the connectingplate 821 and is in threaded connection with the threaded connector.When requiring to be mounted or removed, the entire wheel cover and seatassembly 7 is removed. Specifically, the wheel cover and seat assembly 7is fixed to the C-shaped groove 811 of the first connecting member 81 onthe floor 1 by using the bolt 83. When the wheel cover and seat assembly7 needs to be removed, the sealing plate 34 or the cover plate fordecoration is first removed, and then the bolt 83 such as a fasteningbolt is loosened, so that the entire wheel cover and seat assembly 7 isremoved. A mounting process is opposite to the removal process.Therefore, by using the C-shaped groove 811, the accuracy of positioningthe bolt 83 and the threaded connector can be improved, and the assemblyefficiency is improved. When a plurality of threaded connectors aredisposed in the C-shaped groove 811, the threaded connectors may be nutsfixed to the C-shaped groove 811 or movable in the C-shaped groove 811.In this case, machining precision of a plurality of connecting plates821 can be reduced, and the costs can be saved.

For example, when the threaded connector in the C-shaped groove 811, forexample, the nut in the C-shaped groove 811, is movable, during mountingand removal of the wheel cover and seat assembly 7, the wheel cover andseat assembly 7 may move leftward and rightward along the C-shapedgroove 811. When an assembly error exists, the assembly error can bereduced by moving the wheel cover and seat assembly 7 leftward andrightward, so that the wheel cover and seat assembly 7 is easy toremove. In addition, as shown in FIG. 27 , when a positioningdestination of the wheel cover and seat assembly 7 is a spacer in therailway vehicle such as the straddle-type monorail vehicle, after thewheel cover and seat assembly 7 is mounted in the C-shaped groove 811,the wheel cover and seat assembly 7 may be pushed toward the spacer, sothat the wheel cover and seat assembly 7 is seamlessly propped to thespacer. When the wheel cover and seat assembly 7 needs to be removed,the wheel cover and seat assembly 7 is pushed away from the spacer, sothat the wheel cover and seat assembly 7 is removed.

As shown in FIG. 21 and FIG. 26 , the wheel cover 3 includes a dustproofcover 31 and a wheel cover outer cover 35. The dustproof cover 31 coversthe wheel 2, and the wheel cover outer cover 35 covers the dustproofcover 31. Specifically, for example, the wheel cover outer cover 35 maybe fixedly connected to the dustproof cover 31 by a wheel cover frame36.

Specifically, as shown in FIG. 3 , FIG. 4 , and FIG. 6 to FIG. 11 , eachfixed support 12 includes: a fixed portion 121 and a support portion122. The fixed portion 121 is connected to the side wall 113 of theopening portion 11, one end of the support portion 122 is fixedlyconnected to the top of the fixed portion 121, and the other end of thesupport portion 122 horizontally extends toward the wheel 2. The wheelremoval and mounting floor panel 5 is supported on an upper surface ofthe support portion 122, and the wheel removal and mounting floor panel5 is detachably connected to the support portion 122. For example, inexamples of FIG. 4 and FIG. 7 , both the fixed portion 121 and thesupport portion 122 may be plate-shaped structures, the fixed portion121 and the support portion 122 are generally L-shaped as a whole, andthe fixed portion 121 and the support portion 122 may be processed andformed as a whole. For example, the fixed portion 121 and the supportportion 122 may be formed by bending a flat plate, and the fixed portion121 may be detachably connected to the side wall 113 of the openingportion 11 by a bolt or the like, so that the entire fixed support 12 isfixed to the floor 1, achieving convenient mounting and a reliableconnection. The upper surface of the support portion 122 can support thewheel removal and mounting floor panel 5, and the horizontal supportportion 122 facilitates connection between the support portion and thewheel removal and mounting floor panel 5, so that the assemblyefficiency can be improved.

For example, in FIG. 1 to FIG. 5 , each wheel removal and mounting floorpanel 5 is supported and fixed by two fixed supports 12, and the twofixed supports 12 are respectively located on two ends of the wheelremoval and mounting floor panel 5 in a length direction. Herein, thetwo fixed supports 12 are for the purpose of exemplary description.However, after reading the technical solution of this application, aperson of ordinary skill can obviously understand that the solution isapplied to the technical solution of three or more fixed supports 12,which also falls within the protection scope of the present disclosure.

Optionally, referring to FIG. 4 , FIG. 8 , and FIG. 9 , the uppersurface of the support portion 122 is lower than the upper surface ofthe floor 1 and a distance between the upper surface of the supportportion 122 and the upper surface of the floor 1 is equal to a thicknessof the wheel removal and mounting floor panel 5. In this case, the uppersurface of the support portion 122 is lower than the upper surface ofthe floor 1, and after the wheel removal and mounting floor panel 5 ismounted on the fixed support 12, an upper surface of the wheel removaland mounting floor panel 5 may be flush with the upper surface of thefloor 1.

Optionally, as shown in FIG. 4 , a width of the support portion 122 ofthe fixed support 12 is greater than half of a width of the wheelremoval and mounting floor panel 5. In this way, the floor panel can besupported more reliably. Similarly, to improve the stability of thesupport for the wheel removal and mounting floor panel 5, one end of thewheel removal and mounting floor panel 5 may further be configured in acurved edge or a bevel, as shown in FIG. 4 .

Further, each fixed support 12 further includes: at least onereinforcing rib 123. The reinforcing rib 123 is connected between alower surface of the support portion 122 and a surface on one side ofthe fixed portion 121 adjacent to wheels 2, as shown in FIG. 4 , FIG. 7, and FIG. 9 . Therefore, by disposing the reinforcing rib 123, astructural strength of the fixed support 12 can be improved. Optionally,the reinforcing rib 123 may be a plate-shaped structure. Certainly, thereinforcing rib 123 may alternatively be a rod-shaped structure (notshown in the figure). However, the present disclosure is not limitedthereto.

According to some embodiments of the present disclosure, referring toFIG. 8 and FIG. 9 , an avoiding opening 1231 is formed in thereinforcing rib 123, and the avoiding opening 1231 is located at a jointbetween the support portion 122 and the fixed portion 121. For example,in an example of FIG. 9 , the avoiding opening 1231 may be a triangularnotch. In this case, a gap exists between the reinforcing rib 123 andthe corresponding joint between the support portion 122 and the fixedportion 121. Such arrangement can avoid stress concentration on thejoint between the support portion 122 and the fixed portion 121 andimprove the support reliability of the fixed support 12.

Optionally, the wheel removal and mounting floor panel 5 is connected tothe support portion 122 by a bolt. Therefore, removal and mounting areconvenient, the bolt structure is simple, the connection is reliable,and the costs are low.

Optionally, the fixed support 12 is an aluminum member. However, thepresent disclosure is not limited thereto.

Optionally, referring to FIG. 11 , the thickness of each wheel removaland mounting floor panel 5 is t, and t meets 30 mm≤t≤50 mm. Therefore,the thickness t is set to meet 30 mm≤t≤50 mm, it is ensured that astrength requirement of the railway vehicle such as the straddle-typemonorail vehicle on the floor 1 is met and the costs can be saved. Forexample, when the thickness t is less than 30 mm, the thickness of thewheel removal and mounting floor panel 5 is relatively small, which maynot meet the strength requirement of the railway vehicle such as thestraddle-type monorail vehicle on the floor 1, that is, deformation orcracking may occur when a plurality of passengers stands on the floor,easily resulting in a safety hazard. When the thickness t is greaterthan 50 mm, the thickness of the wheel removal and mounting floor panel5 is relatively large. In this case, the entire wheel removal andmounting floor panel 5 is heavy, and the costs are high. Further,optionally, the thickness t meets: t=30 mm.

Optionally, both the two wheel removal and mounting floor panels 5 arealuminum or steel. An aluminum material and a steel material can meetthe strength requirement well, and the two materials are widely usedwith relatively low costs. In addition, the weight of the aluminummaterial is relatively light, which can meet the lightweight design.However, the present disclosure is not limited thereto.

It can be understood that a shape of each wheel removal and mountingfloor panel 5 may include a straight edge shown in FIG. 4 or may includean arc-shaped or ellipse arc-shaped edge or the like. The specific shapemay be specifically designed according to a condition around the openingportion 11 of the railway vehicle such as the straddle-type monorailvehicle, to better meet an actual application.

According to some embodiments of the present disclosure, as shown inFIG. 1 to FIG. 3 , an overhauling floor panel 4 is further disposed inthe opening portion 11, and the overhauling floor panel 4 may bedetachably connected to a wheel access panel 111. Specifically, theopening portion 11 may include the wheel access panel 111 and a wheelmounting opening 112 in communication with each other. The wheel accesspanel 111 and the wheel mounting opening 112 may be understood asdifferent regions of the opening portion 11. The two wheel removal andmounting floor panels 5 are mounted at the wheel mounting opening 112,the wheel mounting opening 112 (that is, the sub-opening portion) isdefined between the two wheel removal and mounting floor panels 5, apart of the wheel 2 passes through the wheel mounting opening 112 andprotrudes from the upper surface of the floor 1, and the overhaulingfloor panel 4 is detachably connected to the wheel access panel 111.Therefore, after the overhauling floor panel 4 is removed, the wheel 2may be overhauled by using the wheel access panel 111. Specifically,when the wheel 2 needs to be overhauled, for example, daily tirepressure detection, tire inflation and deflation, and pattern depthmeasurement are performed on the wheel 2 such as a walking wheel, theoverhauling floor panel 4 may be removed from the floor 1, and the wheelaccess panel 111 is exposed. In this case, the wheel 2 in the wheelmounting opening 112 may be viewed and operated through the wheel accesspanel 111, to overhaul and maintain the wheel 2. Compared with aconventional manner in which access panels are respectively disposed onthe wheel cover outer cover and the dustproof cover, in the manner, forexample, when the wheel cover 3 includes the wheel cover outer cover 35and the dustproof cover 31, no access panel needs to be disposed on thewheel cover outer cover 35 and the dustproof cover 31, so that thedustproof and sound insulation effects of the dustproof cover 31 can beensured. In addition, the floor panel 4 can be made large, to increasean overhauling space (that is, the wheel access panel 111) for the wheel2, thereby facilitating the daily overhauling and maintenance on thewheel 2.

Referring to FIG. 1 to FIG. 3 , the wheel access panel 111 is located onone side of the wheel 2 in a left-right direction of the railway vehicle100. This arrangement is convenient for maintenance personnel to performoperations such as tire pressure detection, tire inflation anddeflation, and pattern depth measurement on the wheel 2 such as thewalking wheel in the wheel access panel 111.

Optionally, a longitudinal maximum width of the wheel access panel 111is greater than the diameter of the wheel 2 For example, a width of thewheel access panel 111 is greater than the diameter of the wheel 2 inthe length direction of the floor 1, and a size of the wheel accesspanel 111 is relatively large, so that daily overhauling and maintenanceon the wheel 2 can be more convenient.

According to further embodiments of the present disclosure, referring toFIG. 1 to FIG. 4 , the overhauling floor panel 4 may be mounted at theopening portion 11 by using at least one fixed support 12. Further, asshown in FIG. 1 to FIG. 4 , some fixed supports 12 can support both theoverhauling floor panel 4 and the wheel removal and mounting floor panel5. In this way, a quantity of fixed supports 12 can be reduced, and theoverhauling floor panel 4 and the wheel removal and mounting floor panel5 can be more tightly and neatly connected.

Still further, to reduce noise transmission, a sealing member 124 mayalso be disposed between the overhauling floor panel 4 and the floor 1,and the sealing member 124 may be disposed between a lower surface ofthe overhauling floor panel 4 and the upper surface of the floor 1, asshown in FIG. 10 and FIG. 11 .
